After you made and saved the changes (remember CTRL + X from above) restart your Pi using:

sudo reboot

Check if you are connected by using:

ip addr

Or try if you get a signal using

ping google.com

Once you have a function connection run the following two commands to bring your Raspberry to the lastest versions of things:

sudo apt-get update
sudo apt-get upgrade

Optional: Set up a static IP adress (recommended for SSH access)

Considering the Pi being a dashboard an therefore stuck somewhere behind a monitor you want to have a static IP set up for smoother SSH access. However this is optional and SSH connection can also be done with a dynamic IP.

*Be aware that the last command first seems infunctional. Even if nothing happens just wait and let the Raspberry work. After about 10 minutes you will see some installation output on the commandline.

After this you should be finally good to go.

4. Install Chromium Browser

Next up you need a browser and a server for the localhost in order to display the dashboard. I chose Chromium as a browser together with unclutter to hide the mouse cursor, and X11VNC as a XServer. To install these all in one run:

Now the sample.erb dashboard should be loaded in a headless chromium on your screen.

Congrats! You’re running dashing!
